# operator<<(std::filesystem::directory_entry)

From cppreference.com
< cpp‎ | filesystem‎ | directory entry

template< class CharT, class Traits > friend std::basic_ostream<CharT,Traits>& operator<<( std::basic_ostream<CharT,Traits>& os, const directory_entry& d ); |  | (since C++17)

Performs stream output on the directory entry d. Equivalent to return os << d.path();.

This function template is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::filesystem::directory_entry is an associated class of the arguments. This prevents undesirable conversions in the presence of a using namespace std::filesystem; using-directive.

### Parameters

os | - | stream to perform output on
d | - | `directory_entry` to be inserted

### Return value

os

### Exceptions

May throw implementation-defined exceptions.

### Example

Run this code

    #include <filesystem>
    #include <iostream>
    namespace fs = std::filesystem;

    int main()
    {
        const auto entries = {fs::directory_entry{fs::current_path()},
                              fs::directory_entry{fs::temp_directory_path()}};

        for (const fs::directory_entry& de : entries)
            std::cout << de << '\n';
    }

Possible output:

    "/home/猫"
    "/tmp"
